1 is a stationary tank having an open top. 'lhe lower part 2 of one sideof said tank slants inwardly toward the bottom- 3, and a partition 4 issecured in said tank to divide it into twolorigitudinal compartments 5and 6. The lower part of the,compartment 5 has transverse partitions 7,8, 9, and 10 arranged therein, whieh'aiford receptacles 11, 12, 13, 14,and 15, and the latter communicate beneath the lower edgeof thepartition 4 with corresponding rece taeles 16, 17, 18, 19, and 20,.respectively. t will now appear that matter settling in the respectivereceptacles of the compartment 5 will gravitate there- 1 from into thecorresponding receptacles of Ass the compartment 6.

thereof. A series of discharge spouts 22 lead through the bottom 3 ofthe tank, one from each of the receptacles 16, 17, 18, 19, and 20, andeach of said dischar e-spouts is provided with a valve 23, whic i isseated upon the top thereof. The stern 24 of each o said valves extendsvertically in its correspending receptacle, and the upper end of each ofsaid stems has connectionwith an actuating-lever 25, which is adapted toraise the corresponding valve by lifting its stem. The valve-stem is ofsufficient weight as to return the valve to its seat when released bysaid lever. A valve-actuating shaft 26 is rotatively lmounted insuitable brackets 27, which extend from the side of the tank 1, at thetop thereof, and upon said shaft are secured'a series of cams 28, whichengage correspondingly the levers 25 and actuate the same. The said camsare so disposed relative to one another that said levers will becomeactuated in successive order when the lshaft 2.6'is rotated. The levers25 are mounted upon a supporting-shaft 29, which has` end trunnionseccentrically disposed; The said trunnions rest in the adjacent brackets27, and one of said trunnionshas fixed' upon its extending end ahand-,lever 3] by means of which the shaft 29 Inay be turned, wherebyall of the said levers 25 will be raised or lowered, according .to theposition of saidv hand-lever, an'd thus said levers may be brought intoor out vof position for engagement with the cams28, as shown in Fig. 6.

In the upper part of the tank 1 and within the compartment 5 thereof isarranged upon an incline a concentrating-pan 32, which is mounted so asto permit of its being reciprocated. The said panl consists of a thinmetal plate slightly depressed throughout its length and has upturnedsides 33 and two series of The said riflies lead uniformly from. thesides of the pan diagonally downward and terminate at points near themiddle thereof, leaving a -central passage-way 35 throughout the lengthThe lower' `or discharge part efof the pan. the pan is without upturnedsides, and .the

head-casting 37 is rigidly fixed to the upper' part of theconcentrating-pan and hasloos'ely mounted therein a shaftv 38, the endsy of which project from each side ofv said casting. Upon said shaftandbetween the wings 39 of said casting is mounted a bearing-roller 40,

and upon said extending ends of said shaft are loosely mounted therespective supporting-rollers 41. To the under side of the lower part ofthe concentrating-pan is secured a guide-bearing 42, which rests upon agrooved wheel 43, supported in the tank 1 by the.

bracket 44. The said supporting-rollers 41 rest upon guideways 45,afforded by the main bracket 46. The said guideways range in a planeparallel with that of the concentratingpan 32, so that when the pan isactuated it will be reciprocated in the direction of its length. Themain bracket 46 has bearings 47, in which is mounted the driving-shaft48, which has in connection therewith suitable tight and loosebelt-pulleys 49, by which the same is driven. Between the bearings 47upon said shaft 48 is mounted a polygonal driving-cam 50, which actsagainst the said bearing-roller 40 when the driving-shaft revolves. Atension-sprin 51 is xed upon the main bracket 46, an a yoke 52 issecured to the Wings 39 of the head-casting ofthe concentrating-pan, andan adjustable connection 1s made between said yoke and spring by meansof the eyebolt vBy'this means the roller is held against the cam 50 withmore or less force accordingly as the eyebolt 58 is adjusted in theupperend of the spring 51, and because of the tension of the spring theconcentrating-pan tends toward its uppermostplane of'movement. As thecam'50 revolves the concentrating-pan will be rapidly vibrated in thedirection of its length.

U on one end of the driving-shaft e8 is fixe a bevel-pinion 54, whichmeshes with a bevel-gear 55, mounted upon the end el the valve-actuatingshaft 26, by means of which motion is imparted to the latter.

Aprons 56 are secured within the compartment 5, respectively to the tank1 and partition 4, adjacent the sides of the concentrating-pan, and thelower edges of said aprons overlap the upturned edges 83 ofthe pan andserve to direct settling matter onto the concentrating-surface of thepan.

A series of diverting-blades 57 are secured to a suitable frame 58 andare V -shaped and are arranged uniformly. The vertices of saiddiverting-blades are located in line with the middle of said frame, andthe sides thereof range divergently to points slightly beyond the sidesof said frame. The said series of diverting-blades and their suportingframe are made to conform in out ine with the general plan of theconcentrating-pan,

and when placed in position over the pan the said diverting-blades rangeoppositely to the riilles 34, viz: The said riiles converge toward thecenter of the pan, and the diverting-blades diverge toward the sidesthereof.

The said diverting-blades are supported by means of suitable hangers 59,secured, re-

spectively, at the ends of the frame 58, and

vertically adjustable bv means of suitable springs 61 and thumb-nuts 62.l

A screen 63 is arranged transversely in the compartment` 5 Vand rangesin a vertical plane adjacent the hangers 59 at the upper end of thediverting blades, and the lower edge of the screen extends approximatelyeven with the to s of the adjacent ends of the diverting-bla es.

64 is a diHusion-box having an inclined bottom and an open top. Thesides, ends, and bottom of said box are composed of burlaps 65 or othersuitable fabric, suitably reinforced by wire-gauze 66 for the purpose ofsupport. The said box 64 rests upon the top of the frame 58 of thediverting-blades and over the lower or discharge part of the con-Acentrating-pan. l

In the operation of this invention the tank is filled with water to thelevel of its overflowoutlet, and such level is constantly maintained bysupplying a suitable quantity of water to the diffusion-box. The waterthus supplied seeps outward through the sides, ends, and `bottom of thediffusion-box, and thus the necessary supply of water tothe tank iseffected without causing currents which would disturb the ore matterpassingl over the concentrating-pan. While theconcentrating- -pan is inmotion ore-pulp is suitably fed to the machine directly upon the upperpart of the pan at a point between vthe screen 63 and the head-casting37. The pulp thus fed settles upon the pan and moves toward thedischarge end because of the rapid vibration and the incline of theconcentrating-pan rather than because of any movement ot the watercontained in the tank. lt is the intention that 'the water in the tankshall be at all times as motionless as possible. During the passage of'ore-pnl downthe inclined pan the values or minera portion of the pulpwill gravitate and Aform a stratum next the surface of the pan and willbe directed by the convergent rind es toward the central passage-way.35,and the overlying portion ol the pulp,which has thus been relievedol its mineral con-" tents, will be directed toward the sides of thepan. In this manner thev values are carried to the extreme end of thepan, and the more or less valueless ganglio is caused to pass over theconvergent edges 36 thereof. The values discharged from the pointed endof the pan gravitates therefrom into the receptacle 11 and passes intothe receptacle l 6, troni whence it is discharged through the spout 22in the bottoni thereot1 when the corresponding valvel is lifted. The orcmatter discharged from the edges 36 of the pan gra-vitates into thereceptacles l2, 13. 14, and l5, from whence it passes into thecorrespondingr receptacles 17, 18, 19, and 20 and is dischargedtherefrom ICC? IIC

through the spouts inthe bottoms thereof as the corresponding valves arelifted. The proportionlof ore matter `discharged from the extreme pointof the `pan may be varied directly by raising the diverting-blades andconversely by lowering the same.
